The ATM Green Machine by Zink Calls is a double reed duck call featuring the same smooth mallard sound callers have grown to love, but with a great volume and a radically improved bottom-end feed chuckle. This innovative new call is enhanced with Zink's Z-Cut no-stick tone channel, a revolutionary design that permits a huge range of tones, while virtually eliminating reed-lock. Field tested and perfected over the years, the ATM comes complete with extra reeds, instructional DVD, Zink Calls leg band, and a protective hard case.
